New strategy for resource allocation using PSO-PFS hybrid

Abstract

In this paper, the problem of resource allocation in a tri-sectorial cell taking into account the OFDM transmission technique used in wireless network, such as LTE, and the upcoming 5G, is studied. A new strategy for resource allocation scheme based on PSO-PFS hybrid (Particle Swarm Optimisation and Proportional Fair Scheduling) is proposed to help the users who are in a critical location and to have an optimal distribution of resources. The scheme leverages the PFS algorithm taking into consideration the channel state conditions of the users, where the PSO algorithm provides an optimal solution to the allocation problem and improves the performances of users according to their channel state. The simulation results show that the allocation of resources by the PSO-PFS hybrid guarantees a high throughput of the system by ensuring fairness through all users.
